You cannot charge flying up without perfect maneuverability.
Round 537: Dave Thomas flies up to 75N75E30E and whiffs (rolled 13+1=14 for A).
The monkey misses with bite, wing buffet, and two mace swings, but the first mace attack hits, although Dave could have sworn that it missed (rolled 18, reroll rolled 28). The monkey inflicts 13-10=3 points of damage. Dave has 48 HP remaining.
